📖 Magnetic Semiconducting Clusters: A First principle investigation. Structural, Electronic and Magnetic Properties of Doped Semiconductor Clusters.

This book outlines the possibility of combining semiconducting and magnetic functionalities at nanoscale. The pure semiconducting clusters of Ge, C and ZnO have been investigated systematically using density functional theory. The magnetism in these nano-clusters has been incorporated by doping with 3d transition metals, p-block impurities (C, N and B) as well as by introducing point defects. The results have presented an alternate way of inducing magnetism by incorporating magnetic or non-magnetic impurities as dopant and co-dopant in Ge, C and ZnO clusters. The size dependent properties of nanoclusters and effect of point defects are additional factors which influence the magnetic properties of the Ge, C and ZnO clusters. The results of this work are supposed to provide guidelines for realization of spintronic based devices.
